^†Represents the Annual Fund Operating Expenses as disclosed in the current prospectus dated April 30, 2023. It is important to understand that a decline in the Fund’s average net assets due to unprecedented market volatility or other factors could cause the Fund’s expense ratio for the current fiscal year to be higher than the expense information presented. A shareholder may be required to pay a commission to their financial intermediary. Driehaus Capital Management LLC, the Fund’s investment adviser (the “Adviser”), has entered into a contractual agreement to cap the Fund’s current ordinary annual operating expenses (excluding interest, taxes, brokerage commissions, other investment-related expenses, acquired fund fees and expenses,and extraordinary expenses, such as litigation and other expenses not incurred in the ordinary course of the Fund’s business), resulting in the current net expense ratio of 0.76% until the earlier of the termination of the investment advisory agreement, by the Board of Trustees or the Fund’s shareholders, or April 30, 2024. Pursuant to the agreement, and so long as the investment advisory agreement is in place, for a period not to exceed three years from the date on which the waiver or reimbursement is made, the Adviser is entitled to reimbursement for previously waived fees and reimbursed expenses to the extent that the Fund’s expense ratio remains below the operating expense cap that was in place at the time of the waiver / expense reimbursement as well as the current operating expense cap. Because of this agreement, the Fund may pay the investment adviser less than the contractual management fee.
